DA(C)Z Heatless

Heatless adsorption dryers with pressure dewpoints to -70 °C are suitable when D series refrigerant dryers with pressure dewpoints of + 3 to +7 °C will not meet the requirement.

Before drying, the standard BOGE FP series micro-filter removes any solid and liquid impurities up to 0.01 mm from the compressed air supply.
In the adsorption dryer, the desiccant material adsorbs moisture from the air, resulting in clean, dry compressed air. Pressure dewpoints to -40 °C can be achieved with the standard model.

In parallel with moisture adsorption, regeneration takes place in a second vessel. With type DAZ heatless adsorption dryers, compressed air which has already been dried is used to regenerate the desiccant.

BOGE DACZ series Treatment System

DAZ Adsorption Dryer and DCZ Activated Carbon Adsorber with pre-filter and after-filter

Heatless adsorption dryers with builtin activated carbon adsorbers are installed where the compressed air is required to have a residual oil content down to 0.003 mg/m3 and a pressure dewpoint to -70 °C.


Brand: BOGE Category:

The advantages of using the BOGE DAC treatment system are:

  • Complete and ready for use
    – saving on installation and piping costs for pre-filters and after-filters (up to DAZ 160)
  • Generously dimensioned inlet and outlet valves
    – low differential pressure, saving on energy costs
  • Compressor synchronisation control
    – energy saving
  • Robust, flexible adsorption principle
    – maximum availability
  • Microprocessor-based control
    – Adjustment of pressure dewpoint an option
  • Display of function on front panel of switch cabinet
    – Permanently displayed status
  • Regeneration without an external energy supply
    – economic, trouble-free operation
  • 10-Minute Cycle
    – approx. 6% energy saving
  • Optional dewpoint control
    – energy saving by controlling the volume of purge air, depending on pressure, volume and temperature
  • Condensate removed via the purge air
    – no costs for condensate removal / drainage
  • Standard pressure dewpoint -40 °C
    – no condensate formed in pipework installed outside
  • CFC-free
    – significant contribution to protecting the ozone layer and environment
